Cindy is 10 years younger than her teacher. Her teacher is four years younger than her sister. Her sister is twice Cindy's age. How old is Cindy?

Does this bring back nightmares of PSLE problem sums?

Went out with my sis and her student last night. The generation gap is staggering.

While having dinner, her student made sure that there was no vegetables in her meal, because her surname is Cai. I, on the other hand, was having a healthy salad.

While shopping at Tangs later, her student looked on in bored amusement as I excitedly compared bedsheets and threadcounts, and exclaimed over $248 dustbins. And rolled her eyes when I tried on a cheongsam that was on sale.

While driving home, she was utterly aghast that we were listening to Class 95 and proclaimed that she would never ever do that even when she is old. Give her another 10 years, I say, and she'll be humming along to "golden oldies" with us.
